C＃如何打开保存在MemoryStream中的文件（工作簿）而不将其实际保存在服务器中？

Question

I want to Open a file (show an Excel file for user) without having it saved in my computer/server to open it from memory. So far i came up with this code which saves file to MemoryStream:

MemoryStream memoryStream = new MemoryStream();
wb.SaveAs(memoryStream);

So how to open/show a Excel file which is saved in the memory stream

Answer 1

The Excel application can't read from a MemoryStream.

You will have to write the file onto disk, maybe into a temporary directory.
